Can I use K & N filter on stock truck or will service dept. say anything about it ? Also it is hard to find stock replacement filters right now called Autozone and O'reilly No one has any instock. And I am sure Dodge dealer is way to high haven't even called them. Any other filters that people offer on here, I can't afford Scotty yet.

 

Will the BHAF work on the '03? If so use those.

 

I asked the service advisor at my dealership and he held the Cummins party line on K&N filters which can be found here: Cummins FAQ

 

If the above link doesn't convince you, run K&N for a while then send your oil analysis to Blackstone. They'll convince you not to run K&N... K&Ns are for race-only motors. It's sad to see major automotive chains marketing them for street applications!

Why do you say that?

...because it makes no sense on a daily driver to install a filter that significantly reduces the lifespan of the engine. K&Ns started life as racing filters - you don't run a typical race motor for 60,000 miles a year, and you'll likely be refreshing the race motor a lot more often than you'd want to on a daily driver... all this is especialyl true when said filter provides NO discernable difference in RWHP on a dyno... IMO, if you want to allow more airflow for a given particle size filtered, you have to increase the surface area of the filtration media. Enter Scotty, BHAF, etc.

 

Go to genosgarage.com for all your filters and a lot more. I have bought lots of stuff from them and they are great...

I need an air filter right now and I too am trying to decide what type to get. AFE makes one but they want $100.00 for it. I stopped by NAPA today and theirs is $30.00 but they were out of stock.. Summit racing makes one but it is like a K&N only cheaper. I'm hesitant because Cummins specifically states that a filter like a K&N may void your engine warranty....

 

From what I have heard, the filter media in an AFE is pretty much the same as a K&N, so if you don't trust K&N, I wouldn't run an AFE.

I'm a little leery of going to an oilable filter. I've thought about a BHAF, but don't have the time to build my own heatshield, so haven't done that yet either. $100 for a filter and I still have to spend an afternoon trying to fab a sheetmetal box for it? ???

Nothing against Geno's, but you might want to check your local Cummins parts distributor. I get my filters and such from them and they are even cheaper than Geno's - out the door, in my hand when I need them.

I had a 95 S-10 that I put a K&N on when it had 50 miles on it. I sold it with 120,000. Never had any internal engine problems. I lived down 3 miles of dirt road one way back then too.

 

The AFE filter that Geno's stocks for a hundred bucks is the new ProGuard-7. It's a combo filter, five oiled gauze layers and two poly sheets, which makes it a different beast than either the K&N or the (far superior) AFE oiled gauze filters. It's supposed to have far better filtering capabilities than oiled-gauze filters, and better air flow than the BHAF. AFE claims it meets Cummins filtration standards.

I'm always skeptical of manufacturer's claims. However, I ran the BHAF for a year in the dust and salt of western Utah/eastern Nevada, and then switched to the ProGaurd-7 a couple of months ago. I'm running it with a pre-filter. So far, it's done very well, no fines on the inside of the turbo hose, a seat-of-the-pants boost in high-end grunt, and a much louder turbo scream.

 

Sittenbull2,

We too have been a negative posting memeber on the typical 4 layer gaugze filters in the past for the reasons the guys here have stated, way toooooo much dirt got thru. A few months ago AFE designed the Pro Guard 7 and it stops dirt as well as the standard paper filters per the AFE flow and entrapment tests. Since then we have become a warehouse for them and have sold a bundle of the OEM replacement filters as well as the Magnum intake systems with the Pro Guard 7 filters in them. I never though I would be endorsing a gauze filter but this one works and stops the dirt. It's built from 5 layers of gauze, each layer being a tighter weave that the previous one and then two layers of non woven polyester, it works great. The prices you quoted for one of the other brands is quite high, as we sell the OEM drop in in Pro Guard 7 for less than you mentioned. Call us if you have questions at 866-455-7788.

You should be able to buy the BHAF for less than $50! I made my heat shield in 10 mins at work!

just keep the filter clean and it will be ok. Ive had one in my 5.0 for 70k never had any trash in the oil and i drive the heck out of it. ;D just my .02 love the filter in my dodge

I have the drop in replacement aFe filter on my '03 HO, not the pro guard. If it let's anything through that the stock filter didn't, it has NOT shown up in oil analysis. My silicon numbers are as good as or better with the aFe.

...that is definitely a good point, if the gas engine ran that long and stayed healthy with the K&N - did you change the oil consistently, etc.? I took the K&N off my camaro when I did my first oil analysis.

I have KatDiesel's former, slightly-used AFE filter for stock dodge airbox. Are ALL afe filters 7-ply? I'm considering cleaning and using it in my truck... how do I tell how many plies it has? -scott
